NEEDLE-PLATE HOLDER.

. Specification of Letters Patent.

Patented Apr. 19, 1921'.

Application filed December 16, 1919. Serial No. 345,342.

To all whom it may concern:

Be it known that I, RoBnR'rE. GosNnY, a citizen of the United States, residing at Bishop, in the county of lnyo and State of California, have invented new and useful Improvements in Needle-Plate Holders, of which the following is a specification.

This invention is an improvement in attachments for shoe stitching machines, and has for its object to provide a device of this character for permitting the change to be made from a leather or knife needle plate to a rubber or lip rubber plate as may be I required without the detachment of screws or the like.

Other objects and advantages will present themselves as the nature of the invention is better understood, reference being had to the accompanying drawings, in which:

Figure 1 is a perspective view of the attachment.

Fig. 2 is an approximately central vertical longitudinal sectional view through the same.

Fig. 3 is a perspective view of the combined gage and needle plate securing member.

Fig. i is a top plan view of the needle lip plate, the knife needle plate being shown in Figs. 1 and 2.

In the drawings the numeral 5 designates the cap of any well known type of stitching machines. At the front end of the cap, upon the under face thereof may be secured a plate 6, and the top of the cap as well as the said plate may be provided with threaded openings which are spaced but in longitudinal alinement. Two of such openings are required, and the same are preferably threaded receiving therein the threaded shanks of screw members 77. The upper kerfed ends of these members 7 provide outwardly projecting stud portions which for distinction are indicated by the numeral 8. The top of the cap rearward of, but in a line with the studs 8, has an opening therethrough through which is passed a bolt member 9. This bolt member is engaged by a binding nut 10 which contacts with the outer face of the cap and holds the head of the bolt against the inner face of the cap.

The studs 7 are designed to be received in the spaced openings 11 of either the knife needle plate 12 or the spaced openings 13 of the lip needle plate 1%. When one of the plates is thus arranged upon the cap I arrange over the said cap and plate a metallic bar 15 having an elongated slot 16 through which the projecting end of the bolt passes.

The bar 15 slightly to the rear of its elongated opening'has upon its under face a compressible washer or disk 17, while the puter end of the said bar is upset, providmg a lip 18 which serves as a leather guide. On the bolt 1 screw a thumb nut 19, the base portion of which straddling the elongated slot in the bar and binding the bar against the knife needle plate or the lip needle plate, thus effectively sustaining the said plate on the cap. By simply unscrewing the thumb nut the bar may be released from its engagement with the plate, so that one'plate may be removed and another readily arranged on the cap. The compressible washer may be of a slightly greater thickness than the knife or needle lip plates so that the same is compressed against the top ofthe cap when the outer end of the bar is forced against the upper face of the plate. The lipped end. of the bar provides, as previously stated, a leather guide, and with my improvement it will be seen that plates may be easily attached to and quickly removed from the cap of the stitching machine without the requirement of tools and without the removal of screws as is required in the ordinary construction' of such devices.

Having thus described the invention, what is claimed as new, is

In combination with the cap of a stitching machine, of longitudinally alining spaced lugs adjacent one end thereof and designed to be received in the openings of a knife needle plate or a lip needle plate, a headed bolt passing through the bottom of the cap, a binding nut thereon, a bar'having an elongated slot through which the bolt passes, said bar having its outer end formed with an upstanding lip, a compressible ele ment upon the under face of the bar to the rear of the slot therein, thelipped end of the bar adapted to rest onthe plate engaged by the studs, and a winged nut engaging with the bolt and contacting with the bar for compressing the latter against the plate.

In testimony whereof I aflix my signature.

ROBERT E; GOSNEY.
